What is the function rule represented by the following table? x y 0 0 1 -2 -2 4 y = -x - 1 y = -2x y = x - 3 y = -3x + 2

Step-by-step explanation:

Given

x || 0 || 1 || -2

y || 0 ||  -2 || 4

Required

Determine the function rule

First, we have to determine the slope of the function using;

Where x and y represent any two corresponding values of x and y

When x = 0; y = 0  

When x = 1; y = -2  

Substitute these values in

Next, is to determine the function rule; using slope intercept form as follows;

Take any corresponding values of x and y as x1 and x2

When x = -2; y = 4

becomes

Open the bracket

Add 4 to both sides

Hence, the function rule is

i can answer this question sweetie!

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
